E-Prop

The surprising lightness (about 700g) combined with the high resistance of the carbon fiber, has reduced acceleration time of the propeller, providing a quick thrust and an immediate rpm response.
The reduced weight has facilitated the decrease of the moment of inertia (rotational inertia) that is the attenuation of the effect of the propeller torque during acceleration of the engine.
Furthermore, we have taken care of some aspects related to the cooling of the thermic group, through a special profile which increases the air flow in the area adjacent to the hub (extra-cooling).
Also, the area in which the propeller is in contact with the reduction has been studied in order to eliminate aluminum spacer for propeller and to allow a flow of air between the fins of the crankcase, the pulley, and the propeller.
